摘要: 长庆油田主要开采层系中生界侏罗系延9、延10油层组,地层水中普遍含有钡、锶、钙离子,而且含量很高,作为该区注入水的洛河水含较高的硫酸根离子,引起硫酸盐垢沉淀.文中着重研究油田作业过程中BaSO4、SrSO4、CaSO4垢的沉积问题,利用电子计算机来模拟地层水和注入水混合引起的结垢趋势,提出了在油藏不同条件下硫酸盐垢的预测模型和高精度的数值模拟方法,研制了具有全面预测功能的软件系统.

Abstract: In Changqing oilfield,there is a large amount of Ba2+,Sr2+,Ca2+ in formation water and SO42- in the injected water (Luo He water).Since 1979,the sulfate precipitation was discovered in many places of the oilfield.The problem about precipitation of BaSO4,SrSO4 and CaSO4 is considered in oilfield operation.The prediction model and the numerical simulationmethod for sulfate precipitation are studied.
